Концы катушек, стороны которых расположены в пазах 28 и 43, 26 и 45, соединены вместе и образуют зажим фазы С1, а начало одной из катушек, стороны которых расположены в пазах 23,24,25 и 46, 47,48, и конец одной из катушек, стороны которых расположены в пазах 1, 2,3, и 20,21,22, подключены к нулевым выводам 01 и 02.In the first phase, the first stars are included according to coils, the sides of which are located in slots 28 and 43, 23, 24, 25 and 46, 47, 48. The second star includes a coil, the sides of which are located in slots 26 and 45, and opposite it - the coil in the grooves 1,2,3 and 20, 21,22. The ends of the coils, the sides of which are located in the slots 28 and 43, 26 and 45, are connected together and form the clamp of the C1 phase, and the beginning of one of the coils, the sides of which are located in the slots 23,24,25 and 46, 47.48, and the end of one of the coils, the sides of which are located in the slots 1, 2,3, and 20,21,22, are connected to the neutral terminals 01 and 02.

Фазы С2 и СЗ выполнены аналогично причем расположение их катушек по отношению к фазе С1 чередуетс  с интервалом в 12 пазов.Phases C2 and SZ are made similarly, the arrangement of their coils with respect to phase C1 alternating with an interval of 12 slots.

Верхний р д стрелок показывает направлени  токов при питании обмотки через выводы С1-СЗ трехфазным , током (дл  момента времени, когда ток в фазе С1 имеет максимальное значение), откуда видно, что 2Р, 2. Нижний р д стрелок показывает направлени  токов при питании обмотки через выводы 01 и 02 однофазным током, откуда видно, что 2Р, 18.The upper row of arrows shows the direction of the currents when the winding is supplied through the C1-S3 terminals with three-phase current (for the point in time when the current in the C1 phase has the maximum value), from which it is clear that 2P, 2. The lower row of arrows shows the direction of the currents when powered winding through pins 01 and 02 with single-phase current, whence it is clear that 2P, 18.

Вьтолнение обмотки в 48 пазах позвол ет использовать ее дл  другоThe winding implementation in 48 slots allows it to be used for other

го диапазона мощностей машины. Кроме того, выполнение обмотки однослойной значительно уменьшает трудоемкость ее изготовлени .go power range of the machine. In addition, the implementation of a single-layer winding significantly reduces the complexity of its manufacture.

Обмотка может примен тьс , например , в одномашинных преобразовател х частоты и числа фаз, а также в бесконтактных машинах переменного тока с совмещенным возбудителем и др.The winding can be used, for example, in single-machine frequency and phase converters, as well as in non-contact AC machines with a combined pathogen, etc.
